接下来,我将分析实现 RGB 转灰度图像的一段 Python 代码。下面是相关的代码示例: importnumpyasnpfromPILimportImagedefrgb_to_grayscale(image_path):# 读取图像img=Image.open(image_path)img=img.convert('RGB')# 转换为 NumPy 数组pixels=np.array(img)
fromPILimportImageimportnumpyasnpdefrgb_to_gray(image_path):# 加载图像img=Image.open(image_path)# 确保是RGB模式ifimg.mode!='RGB':raiseValueError("图像必须是RGB模式")# 将图像转换为灰度图gray_image=img.convert('L')# 将灰度图转换为numpy数组gray_array=np.array(gray_image)# 复制灰度值以创建...
